- Precise refractive index measurement for gemstones and solid materials determine the refractive index accurately to support identification, grading, and material verification. - Portable and compact lightweight and easy to carry for convenient use in the field, showroom, or laboratory. - Highly accurate readings reliable refractometer performance delivers consistent results for precise gemstone identification. - Quick gem detection identify single gemstones and doublets quickly and efficiently. Use scenarios - Field evaluation at a gem show, mine site, or during procurement use on site to determine refractive index and verify material identity before purchase or assessment. - In-store or laboratory verification rapid, reliable readings during appraisal, grading, insurance, or quality control to confirm gemstone type and eligibility. - Workshop or educational setting convenient tool for gem cutting, setting, and teaching demonstrations to demonstrate material properties and identification.
